STEM-HOLDING DEVICE FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 302,087, dated July 15,1884=.

(Model.

To all whom it may conce n:

Be it known that I, GEORGE THEODORE BAUGHMAN, of Bellefontaine, Logancounty, and State of Ohio, have invented certain new and usefulImprovements in Stem-Holding Devices for Stem-VVinding Watches, of whichthe following is a full, clear, and exact description.

This invention has for its object the production ofa simple, cheap, andefficient means for holding the stem with its. attached crown in thependant of the case of a stem-winding watch; andit consists, mainly, ina collet or ring within the pendant, and through which the stem havingan inner shoulder is fitted to turn freely, said collet being providedwith one or more screws or pins arranged to enter the hole or holes inthe pendant in which the ends of the bow fit. Such construction gives apositive hold of the stem to and within the pendant independently of thebow, yet provides for a ready detachment of the stem and its crown afterthe how has been removed, substantially as hereinafter described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both figures.

Figure 1 represents a face view of a watchcase of a stem-winding watchhaving my invention applied, the pendant being in section. Fig. 2 is alongitudinal section, upon a larger scale, of the pendant, the stem withits attached crown, and the collet on the storm-together with, as shownby full lines, the holding screws or pins of the collet and the bow intheir respective places,

A is the watch-case, and B itshollow pend ant. O is the stem with itsattached crown O.

Fitted loosely around the stein O,within the pendant B, is anindependent stem-retaining collet or ring, D, which may be either madeentire or divided to fit different-sized stems. This collet is arrangedoutside or in the rear of ashoulder or projection, b, on the stem, andis provided with duplicate removable pins or screws 0, arranged so thattheir heads or outer ends enter the holes (1 on the opposite sides ofthe stem, within which the reduced ends of the divided watch-bow E fit.

Instead of duplicate pins or screws 0 fitting both the holes d, thecollet D may only have one of such pins or screws fitting one of saidholes. -This construction, it will be seen,wl ile it in no way restrictsthe free rotation of the stem, positively holds the stem with its crownin place, without being dependent upon the bow E to positively lock itorto hold it in place by mere friction, so that if the bow should becomeaccidentally or otherwise detached it will in no way interfere with thepositive lock or hold of the stem 0 within the pendant, yet in springingthe bow out from its fit within the holes (Z in the pendant B the stemmay be readily detached by simply removing the pin or pins, screw orscrews 0, from the outside of said hole or holes. \Vhen, however, thebow is in place, it will cover or conceal the pins or screws 0.

This improvement may be readily applied to any stem-winding watch atsuch a trifling cost as to be scarcely appreciable.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.111 stem-winding watches, the combination, with thehollow pendant B and the winding-stem O, of the retaining independentcol let or ring D for the stem, said collet being constructedto providefor the free turning of the stem within and through it, and beingprovided with one or more removable pins or screws, 0, arranged to entera side hole or holes in thependant, substantially as specified.

2. In stem-winding watches, the combinationof the independentstenrretaining collet D, having one or more removable and enternally-proj ecting side pins or screws, 0, the stem O, fitted to freelyturn within and through said collet, the hollow pendant B, having sideholes, (l, within which said pin or pins, or screw or screws, arearranged to enter, and the how 1?, constructed to engage with saidholes, essentially as and for the purposes herein set forth.
